TALLAHASSEE -- House and Senate leaders said Wednesday they want to further tighten ethics laws on lawmakers and lobbyists, including rules to make certain legislators were living in their districts.

Last year, the Legislature passed a major ethics overhaul designed to crack down on ex-lawmakers who begin immediately lobbying state government or using their legislative posts to land plum public jobs elsewhere.

At a media planning session Wednesday, Senate President Don Gaetz and House Speaker Will Weatherford said they wanted to go further this year -- and would adopt new rules on their chamber floors defining what is required to establish "residency" and how it would be enforced.

The Florida Constitution requires that lawmakers be "an elector and resident of the district from which elected" and have lived in the state for two years before being elected.

But Florida law doesn't define what it means to be an elector or resident. Lawmakers are currently free to run for districts they don't live in, but must move into them after they're elected. However, the law doesn't dictate how to determine whether they are legally a "resident" of the district. House and Senate lawyers suggested one way would be to require they sell their prior residence, provide proof where their children attend school, show where they receive mail, or prove they are claiming a homestead exemption within the district.

Earlier this month, House and Senate lawmakers filed bills defining residency requirements for lawmakers in the wake of several high-profile cases of lawmakers appearing to live outside their districts.

Sen. Jack Latvala, R-Clearwater, said 10 percent of his co-workers in the Florida Legislature probably don't live in the districts they represent.

He filed a bill to impose a stronger definition of "residency" for elected officials, in the wake of several cases where lawmakers appeared to be representing districts while living outside their borders.

Latvala said he thought 8 percent to 10 percent, or around 12 to 16 House and Senate members, currently lived outside their districts, although he declined to name names and said that was based on "anecdotal" evidence.

Latvala last spring did publicly accuse Sen. Maria Sachs, D-Delray Beach, of living outside her district and renting a home from a friend within the district to appear as if she lived there.

Sachs defeated former Sen. Ellyn Bogdanoff, one of Latvala's political allies, after lawmakers re-drew the Senate maps in 2012.

After that accusation and media reports on other lawmakers, House and Senate lawyers examined Florida's residency requirement and released a memo this week identifying ways lawmakers could tighten the mandate.

Gaetz also said the Legislature would begin auditing lobbyist compensation reports next year -- a requirement passed in 2005 but never enforced.

He also wants to require that special-district lobbyists register and disclose their pay, and for lawmakers who refuse to file financial disclosure reports to be removed from office.
